hi all, thanks for getting back to me. when you say you have a halfcut do you mean a sera or a paseo? if its a paseo I have a 97 paseo which I've removed the engine from so could use the wiring loom from that. I've been told that I need a specific HG thickness does anyone know what that is? also is there a way to see how much the 4efe head can be skimmed? limit markers or something? the plan is to use the 4efe head that is in the glanza atm because I know there is nothing wrong with that one and if I can get it skimmed to up the CR even more. just to clarify 1 thing, apart from the crank, rods, pistons, cams and length of block is everything else on the 4efe and the 5e-fhe interchangeable? where I get my parts from they seem to know nothing about this engine because its not a UK engine and it would make life easier if they are. I took the head off the engine today and found something that I think is really strange, only 3 - 4 of the water galleries were open in the HG the rest were all sealed (not cut out) is this correct? surely it cant be as this would affect the cooling. I cant find out how to upload pics to show you. also some of the lobes in the cam were pitted here and there which is something else i've never seen. all help on wiring to best engine parts to swap and use would be great. thanks
